This is a pure tri-form Warshade, with a bit of PvP ability.
Utility skills are from the Presence pool. You could re-slot to take all the shields if you wanted to play human more frequently.
However, I highly recommend following a Dwarf + 2 Essence pattern where u basically tank for your two essences. If you would rather not do this, or are in a team. Nova is also well slotted, so you'll basically have 3 Nova's as your pets are like your Black Novas.
Dealing with quants on your own can either be done by tp'ing them in, or stealthing right next to them, and holding them. I however, use dwarf form to deal with Quants as the damage they deal you is greatly reduced and you can easily destroy them in Dwarf.
I recommend taking Shadow Cloak, and Nebulous Form. As they are your invisibility in PvP. Nice for running up to a dude and holding him, also the +perception from Shadow Cloak is useful.
I do not recommend taking essence drain. But highly recommend stygian circle as soon as it becomes available. This will negate any stamina issues you may have.
Hope it helps, if you have any questions or need some tips, send me a tell in game @AcidDog
